It’s very old thread. Issue discussed and solved many times since then.

It’s maybe old for you. I use to work with Broadcasting so we always use high res and 16bit so I never got this problem before but when I start lately on web I got this problem.
I solved the problem.
Anyway thank you relying!

You can’t upload one project in different categories unless if you have project for example designed in C4D and AE so AE project with renders version go in category and C4D go in another!!!
Hope you got it.
